for Various Size Workpiece
Machine tool accuracy:
Machine tool accuracy test list (included)
After grinding (grinding) by Hotman's differential grinding
machine, the following requirements shall be met: (Different
grinding wheels shall be used for different materials)
| No. | Model | Work piece | Roundness | Roughness |
| 1. | IC150 | Standard sample | ≤0.002mm | ≤Ra0.25 |
Note: rough grinding (generally grinding amount 0.02~0.05mm); Fine
grinding (generally grinding amount 0.005~0.015mm)
The body and components are cast by Milhanna high grade cast iron
FC30. Components are processed by YASDA, MITSUI SEIKI, TOSHIBA, ELB
and other world-class equipment once clamping processing. Precision
size can be up to micron level, to ensure high precision equipment
basic components.
Machine guide rails and precision ball screws are continuously
lubricated by automatic lubrication system to ensure longer service
life and accuracy. The cooling system is separated from the body to
eliminate vibration and favorable heat dissipation.
Grinding wheel spindle adopts FAG high-precision spindle bearing
sleeve structure, without separate lubrication, simple maintenance,
free of metal-to-metal contact, grinding wheel spindle has the
characteristics of high rigidity and precision, can obtain nearly
permanent service life. For special workpiece grinding, optional
motorized spindle, with the function of increasing linear speed.
Equipped with Siemens 828D CNC automatic grinding system, and
secondary development, man-machine dialogue fool operation, with
many optional equipment to choose.
The grinding feed system is composed of a V and a flat track of
hand-crafted precision shovel, with automatic lubrication system
and C3 level precision grinding ball screw, which can achieve
smooth movement, excellent repeated positioning accuracy and long
track life.
The standard configuration of the grinding wheel spindle is rear
four and rear two bearing structure. High precision dynamic and
static pressure spindle can also be selected, which has the
characteristics of high rotation precision, high dynamic stiffness,
good vibration resistance, high grinding efficiency and good
grinding surface quality. For special work-piece grinding, the
grinding wheel speed can be adjusted, up to 3500 RPM and 60m/s.
Siemens numerical control systemas the standard configuration,
after secondarydevelopment, all Chinese operation interface, easy
to use. Equippedwith Siemens high performance servomotor, the
equipmentCNCsystemanddrivesystemhavebettercompatibility,at the same
time with automatics and repair and automatic compensation
function,to ensure the stability and precision of feed and
grinding.
- Grinding program is created automatically through the user-friendly
interface, using graphical programming tools shopmill / shopturn,
unnecessarily needing special G codes (Optional).
- No need battery or cooling fan. And no need memory battery for the
motor coder.
- Ethernet connector. No capacity limit USB (on line) and CF card.
The programs in USB and CF card can be modified at will. Process
monitor on line. And the data can be saved forever.
- Process showing with animation. High efficiency.
- There are kinds of optional functions, including automatic
end-surface measuring, automatic inner diameter measuring,
hydraulic tail stock, highly integrated auto loading and unloading
system, and so on.
- Automatic wheel dressing and offset. Keep high precision and
stability for the feeding and grinding.
